MACHINE FOR APPLYING PASTE TO PAPER SHEETS.

Application filed June 4,

The object of this invention is to provide a machine for applying pastelongitudinally of a paper strip or sheet being unwound from a roll ofpaper, the adhesive material being ap: plied in a well defined path,near one edge of the strip.

A further object is to produce this result by employing a particulararrangement of rolls, receptacles, and mounting devlces, the pastereceptacle containing the roll for applying adhesive material beingdetachable from the remainder of the structure.

A further object is to provide for guiding the sheets of paper withreference to the rolls.

\Vith the foregoing and other objects in view, the invention consists inthe novel construction and arrangement of elements described,illustrated and claimed, it being understood that modifications may bemade within the scope of the claim without departing from the spirit ofthe invention.

In the drawings forming part of this application,

Figure 1 shows the device in side elevation, a port-ion of the roll ofpaper being broken away.

Figure 2 shows the roll in elevation.

Figure 3 is an elevation of a portion of the structure on which thepaper roll is to be mounted, this View showing the cooperation betweenthe two detachable sections of the device.

Figure 4 is a top plan view of the machine, or the major portionthereof, the standards for supporting the paper roll being in horizontalsection.

Figure 5 is a view partly in elevation and partly in vertical section,showing the relation of the principal rolls over which the paper stripis designed to pass.

Figure 6 is a section transversely of the receptacle adapted to containpaste, and thru two of the rolls, the latter appearing in top plan atthe right of Figure 4.

A roll of paper to which paste or other adhesive material is to beapplied, is designated 10, this roll being carried by a shaft or spindle11 mounted in socket members or bearings such as 12 carried by thestandards 13.

A frame or receptacle 15 serves to mount paste receptacle and thestandards 13, the latter being secured 1926. Serial No. 113,740.

in order to hold the sheet of paper taut, as the latter passes under theroller, and roll or roller 20 is usually of wood, and the sheet passesfrom the lower side of roller 18 to the upper surface of roller 20.These rollers 18 and 20 are journaled in the side walls, or in bearingsin the side walls of the frame or receptacle 15.

A detachable receptacle, usually of sheet metal, is designated 22, andmounts within suitable guiding elements the rollers 24 and 25, thelatter being in a chamber 26 which may be empty, and roll or roller 24being mounted in a paste container 27, it being the intention that thepaste shall be applied by roller 24 to the surface of the sheet ofpaper, near one edge thereon, the width of the surface thus treatedbeing two inches, depending however on the dimensions of the roll 24which may be employed for a given purpose.

Roll or rollers 24 and 25 include axial members 28 and 29, mounted invertical guides such as 30, and each roller carries an outer metallicsleeve or ring such as 31, the roller per se being preferably of wood.

The paper strip or sheet is to pass under guides 35 and 36, and betweenthese elements and guides 37 and 38, the latter extending transverselyof the receptacle 22 and above the upper portion thereof, the projectingends being secured to brackets 39 and 40. A frame connected with theupper edge portion of receptacle 22 includes the side members 41 and 42,and the latter are adapted for connection with the structure 15, in themanner shown particularly in Figures 1 and 2. Slots 43 in side bars 41and 42 permit of engagement by thumb screws 44, passing into thevertical walls of structure 15. Other securing devices are designated45, and these pass thru corresponding elements.

It will be understood that it is only necessary to cause the sheet ofpaper to travel over the rollers 20, 24 and 25, in order to apply thepaste along one edge of the sheet as before indicated, the guidesinsuring sufficiently close contact with the upper surface of roll orroller 24. In this operation roller 25 is used only as an additionalguide.

After the paper leaves the machine, the gummed or pasted margin isattached to a cardboard tube, on which fabric is to be wound. The rolleris mounted on a suitable device for imparting rotary movement thereto,the end of the goods being inserted between the roller and that portionof the paper strip carrying no adhesive material, thus providing as therolling operation commences, for holding the end of the fabric Withreference to the roller.

Having described the invention What is claimed is In a device of theclass described, a structure for supporting a roll of paper, sheetguiding means mounted in said structure. a receptacle detachablyconnected with said structu 'e, the receptacle including a pastecompartment, and an independent compartment, rollers mountedffOl'l'OtiLtlOHflHd for vertical movement in these compartments, meansfor connecting the aforesaid structure and detachable receptacle, andpaper guiding devices each comprising upper and lower plates arranged inpairs, the plates of one pair extending across the adjacent edges of thestructure supporting the paper roll and the detachable receptacle, andbeing secured to the coi'inectingmeans for these elements.

In testimony whereof I afliX my signature.

SAMUEL LOVENWIRTIH.
